logging: added a log on panic
Since panics still regularly "destroy" the terminal, it is hard to get a stack trace for panics you do not anticipate. This commit adds a panic handler that automatically creates a logfile inside the current working directory. It has to be added to every goroutine that is started and will repair the terminal on a panic. Signed-off-by: Moritz Poldrack <git@moritz.sh> Acked-by: Robin Jarry <robin@jarry.cc>
